Rail assembly

ABSTRACT

A rail assembly has at least two hangers, a base and a rail body. Each hanger is a straight slot and has a narrow side and a clamp side longitudinal forming on the hanger. The clamp side is wider than the narrow side. The base has a base body and at least two mounting troughs. The mounting troughs are securely mounted on the base body and each mounting trough corresponds to and is slidably mounted on one of the hangers. The rail body is mounted on the base body. It is only to hang the assembled rail body with the base onto the hangers for assembling the rail assembly without using any tool, so to assemble the rail assembly is easy and convenient.

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to a rail assembly, and more particularlyto a rail assembly that is capable of securely and directly hanging on asidewall without using tools.

2. Description of the Related Art

Conventional rails are securely mounted between cabinets and drawerswith screws and have normally been assembled before furniture been sold.Thus, buyers do not need to worry about assembling problems of rails forthese finished-furniture. However, the finished-furniture is graduallyreplaced by Ready-to-Assemble (RTA) furniture since the RTA furniture isconvenient in use and reduces manufacturing, transport and storage costsand spaces. However, most of the RTA furniture still need tools whenassembling, especially for mounting metal parts on wooden plates, suchas mounting rails on inner surfaces of a cabinet. However, mounting therail on the inner surface of a cabinet at precise locations to makedrawer runs smoothly is not easy for a person who is not skilled inassembling furniture, since the rail is long and heavy but is not easyto leveled on a desired location when using screws to mount the railassembly on a surface.

The present invention provides a rail assembly to obviate or mitigatethe shortcomings of the conventional rail.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a railassembly to improve ease of assembling the rail assembly.

The rail assembly has at least two hangers, a base and a rail body. Eachhanger is a straight slot and has a narrow side and a clamp sidelongitudinal forming on the hanger. The clamp side is wider than thenarrow side. The base has a base body and at least two mounting troughs.The mounting troughs are securely mounted on the base body and eachmounting trough corresponds to and is slidably mounted on one of thehangers. The rail body is mounted on the base body. It is only to hangthe assembled rail body with the base onto the hangers for assemblingthe rail assembly without using any tool, so to assemble the railassembly is easy and convenient.

Other objectives, advantages and novel features of the invention willbecome more apparent from the following detailed description when takenin conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

With reference to FIGS. 1, and 2, a rail assembly in accordance with thepresent invention comprises at least two hangers (10), a base (20) and arail body (30).

With reference to FIG. 3, the hangers (10) are separately mountedparallelly and securely on a surface (40) of a furniture. Each hanger(10) is straight, may be a solid rod or a trough and has a longitudinaldirection, a narrow side (12) and a clamp side (14).

The narrow side (12) is formed along the longitudinal direction and issecurely mounted on the surface (40) of the furniture.

The clamp side (14) corresponds to the narrow side (12), is formed alongthe longitudinal direction and is wider than the narrow side (12).

In a preferred embodiment of the present invention, the hanger (10) is atrack-like track having a bottom surface and two side edges. The bottomsurface is the narrow side (12) to be mounted on the surface (40) of thefurniture. The side edges are parallelly to each other and separate witha distance larger than a width of the bottom surface to form the clampside (14).

The base (20) has a base body (22) and at least two mounting troughs(24). The base body (22) is a straight rod, may be formed by wood,plastic or the like and has a rear surface, a front surface and at leasttwo recesses (222). The recesses (222) are formed in the rear surface ofthe base body (22) transversely.

With reference to FIGS. 4 and 5, each mounting trough (24) correspondsto one of the hangers (10) and has an inner surface, an outer surface, asealed end (242) and an opening end (244).

The inner surface of the mounting trough (24) corresponds to and isslidably mounted on one of the hanger (10).

The outer surface of the mounting trough (24) is mounted on the body(22) and may correspond to and be securely mounted in one of therecesses (222).

The sealed end (242) is above the opening end (244).

The rail body (30) corresponds to and is mounted on the front surface ofthe base body (22).

Take a Ready-to-assemble (RTA) desk as an example, the RTA desk may havea desk body and a drawer. The drawer is slidably mounted on the deskbody with the rail assembly in accordance with the present invention.When a person buys a RTA desk, he/she may get the desk body with hangers(10) mounted at desired locations and the rail body (30) mountedsecurely on the base (20). It is only to hang the assembled base (20)with the rail body (30) onto the hangers (10) for assembling the railassembly without using any tools.

Even though numerous characteristics and advantages of the presentinvention have been set forth in the foregoing description, togetherwith details of the structure and function of the invention, thedisclosure is illustrative only. Changes may be made in detail,especially in matters of shape, size and arrangement of parts within theprinciples of the invention to the full extent indicated by the broadgeneral meaning of the terms in which the appended claims are expressed.
